Per capita personal income growth slowed in most Michigan counties last year.

Chippewa County in the Upper Peninsula saw the biggest annual increase of 6.1 percent to $29,943 in 2012, according to data released Thursday by the U.S. Bureau of Economic Analysis. That's compared to a 1.4 percent increase in 2011.

But most counties didn't see that kind of income growth.

Missaukee County, near Cadillac, actually fell 2.1 percent to $26,884 — the only county to experience a drop in per capita personal income — after experiencing a 6 percent increase in 2011.

Personal income includes proceeds from all sources, including wages, rental income, dividends, interest and other sources. Per capita personal income divides the total dollar amount by the population.

Michigan's per capita personal income rose 3.4 percent to $38,291, after increasing 5.5 percent in 2011, according to revised estimates.
